I have a 1999 Mercury Grand Marquis vehicle. How do you know when the water pump is going. Is their any particular noise I should be hearing.
There is no noise associated with a water pump going out that I am aware of other than the engine exploding due to excessive heat. The dash guages; especially the engine temp guage, will give you a clue as to a cooling problem, whcih is what the water pump is for. The water pump prevents the engine block from overheating. When the pump fails, the engine overheats and will either shut down, or the engine will burn out. The best way to tell is to monitor the temp guage. If the engine is running hot, it either the water pump, lack of water in the cooling system, or Thermostat failure. Best to have a mechanic check it out. Cheers!
